HARROW-FOLIDING DEVICE.

T0 I! whom v't may concern Be it known that I, PIi'l'l-IR Flscnnn, a citizen of the United States, residing at Carroll. in the county of (,arroll and State of Iowa. have invented certain new and useful Improvements in lTarrow-Folding Devices, of which the. following is a specification, ret'erence being bad therein to the accolnpanving drawing.

This invention relates to harrows and has for its object to so arrange and connect a number of harrows that they may extend in a transverse line and when necessary to reducethe width of said line a portion of said barrows may be moved to positions which will reduce the width of the transverse line of barrows.

The invention further has for its object to provide a gang of harrows so connected and arranged with reference to the draft bar of the gang of'harrows that the draft bar may be reduced in length and a portion of said barrows moved to the rear of the gang of harrows.

Referring to the accompanying drawings: Figure l is a plan view of a gang of barrows connected to a draft bar and arranged in accordance with this invention. Fig. .2 is a. plan view of a gang of barrows connected to a draft bar and arranged in accordance with this invention, and showing a portion of said barrows located behind the other barrows. Fig. 3 is a plan view of the 'hinge constructed in accordance with this inven tion with its inembers separated. Fig. 4 is an edge view of the hinge.

In carrying out the invention a number of quadrilateral harrows 1 of any suitable shape and construction are arranged in line, each of said harrows being connected iifany suitable manner to a draft bar 2, and, as here shown, preferably by means of links 73 secured to the bar 2 and rods 4 on the harrows 1, having at one end a book 5 whichengages the loop 3. Under certain circumstances it may become necessary to reduce the length of line of harrows, or, in other words, to reduce the widths of the gang of harrows so that they may pass through a gate or other narrow passageway and also Where it is desirable to have barrows located behind barrows. For this reason the draft Serial No. 654,300.

bar .2 is formed with a hinged section 6 at each end which is connected to the main portion of the bar 2, by a'suitable hinge. and, as here shown, preferably by means of the hinge 7 consisting of the members 8 and 9, each to'rn'ied of a box shape to tit over the section ti and the main portion of the bar 2 and secured in place by rivets or other suitable means. The member 9 is formed with the projections 10 each having a hole 1.1 and the member 8 is formed with pairs ofprojections 12, each having a hole 13, the projections 10 being seated between the pro jections 12 with the holes 11 in the projections 10 being in alinementwith the holes 13 in the projections 12. The parts are' connected together by a pin l-t extending through the hole 11. in each projection .10 and through the holes 13 in each pair of projections 1'2 on the members 8 and 5 \Vhen it is desired to reduce the width ot' the gang of harrows one of the pins 1! is removed from the members S and 5) so that the sections (3 may be swung to the side of. the gang of barrows, as shown in Fig. 9.

In order to relieve the strain on the hinges and tobrace the section tithe dra t't rods 15 are so disposed that oneot each pair is secured at one end to the main portion of the bar 2 and the other of each pair is secured to the hinged section (3. \Vhen i1 is desired to reduce the width of the gang of barrows one or both of the hinged sections t may he nnt'astened by removing the pin 14 and the harrow attached to the hinged section 6 is unhooked at its inner side from the link 3 and moved back to the position, shown in Fig. 2 and held in such position by the hook 5 of the inner rod t engaging a book 15" on the end of a wire or cord 16 secured to an adjacent harrow extending from the main portion ot the beam It will be seen from the foregoing description that the gang of harrows may be "readily increased or decreased in width.

What I claim isz in a gang of barrows ot the character described, a barrow dra t't bar made in sections, the main section carrying at each end one member of a hinge, the outer drat't bar scctions carrying the other members ot said hinges, dratt links connected to the front side of said draft bar, links connected to the trailing section being connected to a link on rear side of said draft bar, inner and outer the draft bar. t 10 harrow sections having hooks on their front In testimony whereof I herennt o attix my ends detachably connected to said rear signature in presence of two Witnesses. 5 links, a hook on the rear part of an inner PETER FISCHER.
